I found some information about deleting closed tabs from Firefox.

Please allow users to select a date or date range instead of a maximum number of tabs and windows. Computers often restart, for instance when installing updates, and some sessions will include more tabs than others.

Thanks in advance!

I can not seem to find the button to open a saved, closed tab group. I have googled, and there seems to be a lot of people with the same issue. However, None of the information given under those forums provides me with a clear, easy solution. Please help.

Malwarebytes is picking up and blocking an outbound connection request from Firefox - www.highperformance.com. Anyone else experiencing this?

I really can't add to my Summary other than it's a fairly recent issue, started in May 2026, possible April. About.config is set to False. I hope some has a solution - it happens when I'm dealing with live incidents.

I've been a loyal Firefox user since version 2.0. but to this day you guys have not made it easier for users to restore Firefox profiles. We in 2026 should be able to do the following directly from the user interface of Firefox. honestly its really taken me a long time to voice this opinion but it makes the app a tad less user friendly. i mean its easier to import from another browser but you have to pull out and search all sorts of folders to import from an old Firefox installation or a windows refresh (windows.old). Please, please implement this ASAP. we users have waited too long.

1. display a list of profiles (even from windows.old after a windows refresh) 2. automatically import that information 3. append existing bookmarks from the bookmarks backup if i choose to. 4. be able to browse the bookmarks and show the most recently used ones 5. be able to even reinstall the existing plugins (this one is minor)

the image attached is exactly showing what happens after a windows refresh. this feature is also great for administrators.

Does Firefox VPN not work with DNS over HTTPS set to Max Protection, and when using a custom provider?

With the VPN on and DNS over HTTPS set to Max Protection set to custom provider, no pages will load and I get an error screen/can't connect to proxy screen.

I use eBird extensively. When I try to play the audio (with sonograms), I get a message that says "We are still processing this file. Try again later". These files perform well on my Android phone, so I know it it is not eBird's glitch. I am confused about the setting options on Firefox that I need to set. These files are usually .wav format. I have tried to open a ticket with eBird, but have not had a response. Can you guide me? Thanks.

I have all the location settings I can find on my Firefox browser, google, and device turned off, but the new firefox weather widget still had my hometown as the default location, which is is not the same location as my IP address. And when I went to buy a book online through Thriftbooks with a guest account the address line autofilled with addresses in my hometown. I do not have any addresses saved to autofill. Where is this information being stored and how do I get rid of it?? Is there something in about:config I can shut off or disable?

Thank you for your time and assistance.

How do I stop this page from coming up several times a day. I have already set FireFox as my default browser, several times, but to no avail. I've careful followed your instructions. I dislike MS and have used FF for years. If this doesn't stop, I'll search for another browser that hopefully behave. I have set it on 4 computers, 2 Win 10, 2 Win 11.

By the way, the computers show FireFox twice, but only one actual installation.

Please do better!

I have ran into a peculiar problem where special characters from non US keyboard do not work in search. In my case it is ％ for TABS specifically (instead of english %). I wanted to correct the problem by changing 'Keyword' field in 'Search Engine' but it is read-only for browser functions. Is there a workaround or a solution I'm missing? Thanks for your help

I am unable to log into my energy provider, when I log into my bank I can't use some features like seeing all my transactions, I can't log into Twitter, I can't play anything from Substack.

My mac froze, force quit did not work, unplugged it, turned it back on, all bookmarks were gone and not able to add new ones. Would like to restore old bookmarks and add new ones.

For 24 hours now I have not been able to connect to Facebook via Firefox browser on my laptop at all. I can connect on my phone, but not my laptop. I've made sure there are no extensions on my browser, my firewall is off, all cookies and cache have been cleared, I even Uninstaller Firefox and reinstalled it. When I try to bring up Facebook, nothing happens. It won't even bring the page up. All other websites work fine. I can't even bring up Facebook to clear the caches in Facebook per the troubleshooting guide. It says to open Dacwbook and click the lock on the address bar, but I can't even open Facebook. What am I missing here?
